摘  要：
为考察不同采收年限(割龄)和月份对PR107橡胶树产胶量的影响,采用统收统测法对1~37 a割龄和5~12月份PR107无性系树位的干胶产量进行测定分析。研究表明,不同年限、不同月份的PR107橡胶树的干胶产量均有明显差异,其中,不同采收月份中,11月份干胶产量最高,其株产、公顷产干胶量分别达798.74 g、169.35 kg,5月份干胶产量最低,其株产干胶量和公顷产干胶量分别为402.70 g、83.45 kg。不同采收年限中,37 a的全年月均株产干胶量最高,达1 334.39 g,34 a的全年月均公顷产干胶量最高,达188.10 kg。各年限PR107的月株产干胶量与月公顷产干胶量呈极显著正相关(P<0.01),而且割龄与年株产干胶量呈极显著正相关(P<0.01),但与年公顷产干胶量则呈显著负相关(P<0.05)。研究初步证明采收年限和月份显著影响橡胶树PR107的干胶产量。

摘  要：
To investigate the effects of different harvest years( tapping years) and months on dry rubber yields per area in PR107 of Hevea brasiliensis,the authors determined and analysed dry rubber yields of PR107 with 1-37 tapping years and 5-12 months by measuring task production.The results showed that there was significant difference in dry rubber yield of PR107 among different harvest years and months,among which the highest production per tree a month and yield per hectare per month in November was 798. 74 g and 169. 35 kg,respectively,the lowest being 402.70 g and 83.45 kg,respectively,in May.The highest yearly mean dry rubber production per tree a month was in 37 tapping years( 1 334.39 g),while the highest yearly mean dry rubber yield per hectare per month was in 34 tapping years( 188.10 kg). There was high significant positive correlation between dry rubber production per tree a month and dry rubber yield per hectare per month,and the ages of tapping were very significantly positive correlated with dry rubber production per tree a year,but had significantly negative correlation with dry rubber yield per hectare per year. This preliminary study shows harvest years and months have a significant influence on dry rubber yield in PR107 of Hevea brasiliensis.
